The inner 'of the stems39 and 40 project into position for engagement with the elongated end or the switch arm to litt said arm out of engagement with 'the insulated sleeve 44, which is carried by another post 45, oi the frame. The face oi the' dial 22 is divided diametrically into l two portions, one of which is white, while the other is black, as

clearly seen in Figure l, the slot 43 being formed imthawhite portion, while a series of internally' Il:threaded openings 45 are formed in the black portion, adjacent the periphery thereof. Thersstems are adapted to be engaged in these openings 46 and into the openings in the ends et the radial arms 37 and 38. The adjustments of the stems in the slot 43 areor the daylight hours, while the adjustments of the stems in the openings 46 are for the night hours. The dial 22 is driven by the minute 'hand arbor, and thereby rotates synchronously therewith.

The screr7 plug 36 being properly screwed into an electric socket, and the current turned'on, the heads 4l and 42 are loosened 'so that the operator may move the stems in the slot 43to the desired hour marked on the dial 22. lf the lights of` a store are to be `turned on at 7 oclocir in the evening, the

white head is moved until it is opposite the number 7 in the black portion of thedial, after which the black head is moved until it is opposite the desired hour for the. lights to be turned off, which may he 5 oclock in the morning. As the clocliF train turns the hands about the. main dial, and the hour ot 7 oclock is reached, the inner end of the stem 39 will engage with the elongated portion oi' the switch arm 28, elevating the same from the sleeve 44. Upon contact of the stem 39 with lthe arm 28, a circuit is completed througllfthe frame of the clock, the wires 18 "and 30, the dial 22, its shaft, the stem 39,

and arm 28, whereupon the'lamps will be Vlighted in the store. As the dial 22 continues to rotate the circuit will remain closed and the arm 28 be nally released from the A stem 39, to fall upon the stem 40, which has,

by this time reached the proper position for this ,operation The arm 28 is again litte'd bythe stem 40 and held in such position, toy

retai'n'the closed circuit, and the lamps in lighted condition, until saidv stem has passed rom bcneaththe other end of the elongated portion of the arm, whenfsaid arm will fall onto the insulated sleeve 44, thus breaking the circuit and extinguishing theilamps.

The elongated end of the switch arm :isnt` Y suiiicient length to permit the stem 39 to remain in contact therewith for a period oi four or more hours, andat the end of this period, when the arm is released from the stem 39, it falls onto the stem 40, so that the circuit is held closed for another period of hours, which will vary in accordance with the position of this stem with relation to the stein 59.

` To normally urge the arm 28 downwardly against the insulation 44, a coil spring 47 is connected to the arm 28, at one end, and has its other end disposed through the insulated bushing 48, into metallic contact with the adjacent end of the wire 18, also secured in said bushing. By this metallic contact between the spring and the wire, current is transmitted to the switch arm 28.

Within the pivot opening of the arm 28 is an insulated bushing 49 which is engaged on the stub shaft 27 a nut 50 being engaged on the rear end of the shaft, while a nut 5l. is engage on the forward end thereof, the `former cooperating with a ange 52, on the shaft to hold the shaft on the frame l5.

What is claimed is:

l.k A time switch including a pivoted arm having elongated terminal, a. rotatable member, an insulated member normally engaged by said terminal, 'and a pair of spaced and adjustable contacts on the rotatable member one of which is arranged to engage the terminal and .move the arno away :from the insulated member to close a circuit for a predetermined period of time, the other contact being arranged'to engage the said terminal immediately upon release from the first Contact to hold the arm away from the insulated member and to maintain the circuit closed for a-second period of time andthe dial thereof having an opening adjacent V.its periphery, of a dial operated by the clock train and rotatable within the opening of the iirstdial, said second dialhaving a shaft, and openings adjacent its periphery, contact pins adjustable in the openings of the second dial, an insulated stop member, and. a pivoted switch arm having an elongated free end normally resting on said stop member and being arranged to be engaged and ele* vated successively by the contact pins whereby to close and maintain a circuit during a period of time determined by the position of said contact pins.
